Personally, I'm hoping they also give enemies Defense, even though that would mean that we won't necessarily know exactly how much DPS we'll be doing on a given boss, short of doing the SSS for that boss, and make Defense linear with eHP instead of %mitigation. In that way they can turn skills like Foe Requiem and Trick Attack into Defense down and it would necessarily have a lesser reduction on 8-man bosses than on 4-man bosses simply because the prior would have more Defense, (and reducing the enemy from, say, 9k to 8k will mean a whole lot less than 4k to 3k). Thereafter, we can apply splitting scalars of a sort to raid buffs as not to overbuff supportive classes in 8-man content or undertune them in solo- or 4-man content.
